FIELD OF THE DISCLOSURE

The subject disclosure relates to a method and apparatus to deliver a personalized media experience, including personalized advertisements.

BACKGROUND

Video content is typically distributed using one of two mechanisms: progressive video and streamed video. Progressive video content is delivered as a series of files (or a playlist of files) that are fetched by a client from a server. This permits dynamic changes in video resolution and bandwidth, as well as insertion of custom advertisements and/or content. Streamed video can be delivered efficiently by multicasting.

DETAILED DESCRIPTION

The subject disclosure describes, among other things, illustrative embodiments for a hybrid multicast/unicast content distribution system that delivers content from a content provider to a client—for example, a set top box (STB)—in a series of files rather than a continuous MPEG transport stream. In an embodiment, a linear television viewing experience is provided that gains efficiency from multicast delivery, and is also enhanced with capability to insert personalized ads, recover from lost multicast frames, and allow channels to be changed quickly. Other embodiments are described in the subject disclosure.

One or more aspects of the subject disclosure include a playlist identifying a series of files, including program files and advertisements. The playlist can be personalized to the client, and accordingly include file identifiers for personalized advertisements. The playlist includes a locator (e.g. a uniform resource locator or URL) for each file. This permits the client to obtain content (e.g. targeted advertisements) as in a unicast environment.

One embodiment of the subject disclosure includes a server comprising a memory that stores instructions and a processor coupled to the memory. The processor, responsive to executing the instructions, performs operations. The operations comprise encoding media content to generate a plurality of media content files, each having a media content filename and a media content uniform resource locator. The operations also comprise providing a playlist for use by a client media processor; the playlist comprises a personalized content filename and a personalized content uniform resource locator for a personalized content file. The personalized content file is not included in the plurality of media content files. The operations further comprise multicasting the plurality of media content files so that the client media processor receives the plurality of media content files, and delivering the personalized content file for storage at the client media processor to enable presentation of personalized content in accordance with the playlist.

One embodiment of the subject disclosure includes a method comprising encoding, by a server comprising a processor, media content to generate a plurality of media content files, each having a media content filename and a media content uniform resource locator. The method also comprises receiving a channel request from a client media processor, and generating a playlist for use by the client media processor. The playlist is mapped to the requested channel, and the playlist includes a personalized content filename and a personalized content uniform resource locator for a personalized content file; the personalized content file is not included in the plurality of media content files. The method further comprises receiving a file request from the client media processor in accordance with the playlist, multicasting the plurality of media content files so that the client media processor receives the plurality of media content files, and delivering the personalized content file to the client media processor to enable presentation of personalized content in accordance with the playlist.

One embodiment of the subject disclosure includes a machine-readable storage device comprising instructions which, when executed by a processor, cause the processor to perform operations. The operations comprise encoding media content to generate a plurality of media content files, each having a media content filename and a media content uniform resource locator. The operations also comprise receiving a channel request from a client media processor, and mapping the channel to a playlist comprising a personalized content filename and a personalized uniform resource locator for a personalized content file. The personalized content file is not included in the plurality of media content files, and the playlist is limited to use by the client media processor and not by other media processors. The operations further comprise receiving a file request from the client media processor in accordance with the playlist, multicasting the plurality of media content files so that the client media processor receives the plurality of media content files, and unicasting the personalized content file to the client media processor to enable presentation of personalized content, in response to the file request.

FIG. 1 schematically illustrates a system 100 for providing video programs and advertisements including personalized advertisements, according to an embodiment of the disclosure. In this embodiment, a client executes on a media processor, depicted in FIG. 1 as a set top box (STB) 101. The STB includes a cache memory 102 and has a program guide 103. The STB 101 is coupled to a display device 109 for presenting video content (generally, programs and advertisements) to the user. In an embodiment, the user can select a program from the program guide to be presented on display device 109. In another embodiment, the user selects a channel over which programs and advertisements are transmitted; the channel selection 105 is communicated to a service provider 150.

The selected channel is mapped to a playlist 120 that identifies files containing the program and advertising content for that channel. In this embodiment, the STB 101 fetches the playlist from the content provider. In another embodiment, the program guide 103 (which has a list of all programs on all available channels) includes a URL specifying a location from which the playlist can be retrieved.

In this embodiment, the playlist 120 identifies a series of files to be fetched by the client, e.g. from cache 102. The files contain MPEG encoding of program and advertising content for the channel and also specific to the user (according to user preferences accessible by server 150). Each file includes a locator, such as a URL, so that the client can obtain the file if it is not automatically provided. In an embodiment, content files 110 with programs and advertising not personalized to the user (that is, default advertising) is delivered to the client in a multicast 105, while files for a personalized advertisement 140 are obtained via network 130 in a unicast 135.

FIG. 2 schematically illustrates a process 200 for encoding and delivering program and advertising content, in accordance with an embodiment of the disclosure. An MPEG encoding process 215 is performed on a sequence 210 of program and ad content, generating a set 220 of MPEG transport streams (MTS) corresponding to the separate items of content in sequence 210. In this example, a personalized advertisement 213 is to be presented to the user in place of default advertisement 212. Advertisement 213 is also encoded to generate an MTS 223.

It will be appreciated that the content sequence 210 is not encoded into a single transport stream (as in multicast linear video), but instead is encoded into a plurality of different MTS, so that program and advertising content remain differentiated (that is, program semantics are preserved).

The MTS sequence 220 is then converted by process 225 into a series 230 of files. The files are intentionally aligned with program semantics. The concatenated files contain MPEG encoding that is identical to an MPEG transport stream encoded from sequence 210 in a multicast linear video environment. In addition, the MTS 223 representing the personalized advertisement is converted into file 233.

The client executing on the STB 101 can then request the files from the service provider, in accordance with the playlist 120. In an embodiment, the service provider responds to the request by joining the client to a multicast group, to deliver the program files and default advertising files by multicasting 235 to all viewers of the channel. The program content and default advertisements are delivered as multicast packet frames 240; in an embodiment, the frames are multicast as IP packets.

In this example, the playlist 120 does not include advertisement 212, but instead includes advertisement 213. The file 233 for this advertisement is not included in the multicast, but is converted into packets 243 so that it can be delivered by unicast. The client then presents packets 243 at display device 109 in place of packets 242 that correspond to the default advertisement 212.

In an embodiment, multiple users may have the same specific advertisement 213 on their playlists. In this situation, packets 243 can be distributed to those users by multicast.

In an embodiment, file 233 may be pre-positioned in the cache 102 of the client STB, so that it need not be sent in real time. More generally, the files 230 (multicast as packet frames 240) can be sent to the client for storage in the cache 102 in advance of a playlist request. In this embodiment, the client can retrieve successive files (corresponding to program sequence 210 for the channel) from the cache, or alternatively from the unicast network 130. This provides a reliability mechanism in case of packets lost from the multicast streams. If a file is not delivered to the cache because of a dropped packet, then the client misses the cache and requests that the file to be delivered using unicast. Similarly, in this embodiment, the client may fail to retrieve a file corresponding to a personalized advertisement from the cache; the client can use the URL associated with that file to obtain the advertising content via a network.

FIG. 3 shows a flowchart of a method 300 for delivering program content and personalized content (including advertisements), in accordance with an embodiment of the disclosure. In step 302, the program content is encoded, along with default advertisements. The encoded content is generated as a plurality of distinct MPEG transport streams (step 304) so that programs and advertisements, and their sequence, remain distinguishable—that is, program semantics are retained. The program and advertising content, represented as MPEG transport streams (MTS), is arranged as a series of files intentionally aligned with the program semantics (step 306). In this embodiment, a channel selection is received from a client executing on a STB (step 308); alternatively, a specific program may the selected by the client from a program guide accessible by the STB.

The channel is mapped to a playlist that identifies a series of files to be retrieved for presentation at the client display device (step 310). Those files, when concatenated, contain the MPEG encoding identical to the MPEG transport stream in a multicast linear video environment—but specific to the client requesting the channel. Different clients may receive different playlists which contain different advertisements for what is otherwise the same program material; in this embodiment, clients requesting a given channel all have the same files for program material on their playlists (common program files for that channel).

In this embodiment, the program guide includes a locator (e.g. a URL) indicating a location from which the personalized playlist can be retrieved. The client obtains the playlist (step 312) and follows the playlist to request files from the service provider. The service provider receives the request (step 314) and recognizes the request by instructing that client to join a multicast group (step 316) which is used to deliver the common program files to all STBs where the channel has been requested. The common program files (as well as files representing default advertisements) are delivered using multicast frames and are sent once to all of the STBs requesting the channel (step 318). Personalized advertisements are embodied in files delivering different content to different clients. Those files may be delivered using unicast, or multicast if they are modest in number, or may be pre-positioned in the client (e.g. STB) cache so that they need not be delivered in real time.

In this embodiment, the files for the program material are transmitted to the requesting clients in advance of their scheduled display (step 320) and stored in local cache at the respective STBs, so that a client can find the next file in their playlist to be in the local cache when needed. If the file is found in the cache (step 322), it is retrieved from the cache (step 328) for display at the display device (step 330).

If the required file is not found in the cache, the client uses the file locator (e.g. URL) in the playlist to retrieve the file via the network (step 324). This can occur when the next file in the playlist is a personalized advertisement and thus not included in the multicast. In addition, a multicast file might not be delivered to the cache because of a dropped packet (this is referred to as a “cache miss”). In either of these situations, the client can request the required file to be delivered to the cache using unicast (step 326). This procedure thus provides an additional reliability mechanism for packets that may be lost from the multicast streams (for example, when the client misses packets belonging to the first file after joining the multicast group).

It will be appreciated that this method can also revert to progressive streaming for networks that cannot support multicast. Accordingly, a single type of video client (e.g. STB) may be used in both multicast and unicast systems.

FIG. 4 depicts an illustrative embodiment of a first communication system 400 for delivering media content. The communication system 400 can represent an Internet Protocol Television (IPTV) media system. Communication system 400 can be overlaid or operably coupled with system 100 of FIG. 1 as another representative embodiment of communication system 400. For instance, one or more devices illustrated in the communication system 400 of FIG. 4 can operate as a server comprising a memory that stores instructions and a processor coupled to the memory, in which the processor, responsive to executing the instructions, performs operations. The operations comprise encoding media content to generate a plurality of media content files, each having a media content filename and a media content uniform resource locator. The operations also comprise providing a playlist for use by a client media processor; the playlist comprises a personalized content filename and a personalized content uniform resource locator for a personalized content file. The personalized content file is not included in the plurality of media content files. The operations further comprise multicasting the plurality of media content files so that the client media processor receives the plurality of media content files, and delivering the personalized content file for storage at the client media processor to enable presentation of personalized content in accordance with the playlist.

The IPTV media system can include a super head-end office (SHO) 410 with at least one super headend office server (SHS) 411 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent, for example, audio content, moving image content such as 2D or 3D videos, video games, virtual reality content, still image content, and combinations thereof The SHS server 411 can forward packets associated with the media content to one or more video head-end servers (VHS) 414 via a network of video head-end offices (VHO) 412 according to a multicast communication protocol.

The VHS 414 can distribute multimedia broadcast content via an access network 418 to commercial and/or residential buildings 402 housing a gateway 404 (such as a residential or commercial gateway). The access network 418 can represent a group of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provide broadband services over fiber optical links or copper twisted pairs 419 to buildings 402. The gateway 404 can use communication technology to distribute broadcast signals to media processors 406 such as Set-Top Boxes (STBs) which in turn present broadcast channels to media devices 408 such as computers or television sets managed in some instances by a media controller 407 (such as an infrared or RF remote controller).

The gateway 404, the media processors 406, and media devices 408 can utilize tethered communication technologies (such as coaxial, powerline or phone line wiring) or can operate over a wireless access protocol such as Wireless LAN (WiFi™), Bluetooth®, Zigbee®, or other present or next generation local or personal area wireless network technologies. By way of these interfaces, unicast communications can also be invoked between the media processors 406 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.

A satellite broadcast television system 429 can be used in the media system of FIG. 4. The satellite broadcast television system can be overlaid, operably coupled with, or replace the IPTV system as another representative embodiment of communication system 400. In this embodiment, signals transmitted by a satellite 415 that include media content can be received by a satellite dish receiver 431 coupled to the building 402. Modulated signals received by the satellite dish receiver 431 can be transferred to the media processors 406 for demodulating, decoding, encoding, and/or distributing broadcast channels to the media devices 408. The media processors 406 can be equipped with a broadband port to an Internet Service Provider (ISP) network 432 to enable interactive services such as VoD and EPG as described above. In an embodiment, the satellite broadcast system can be used to efficiently distribute the multicast groups by associating the multicast packets with a channel that is received over the air (OTA). In this instance, a multicast join process would be replaced with a tuner channel change.

In yet another embodiment, an analog or digital cable broadcast distribution system such as cable TV system 433 can be overlaid, operably coupled with, or replace the IPTV system and/or the satellite TV system as another representative embodiment of communication system 400. In this embodiment, the cable TV system 433 can also provide Internet, telephony, and interactive media services. System 400 enables various types of interactive television and/or services including IPTV, cable and/or satellite.

The subject disclosure can apply to other present or next generation over-the-air and/or landline media content services system.

Some of the network elements of the IPTV media system can be coupled to one or more computing devices 430, a portion of which can operate as a web server for providing web portal services over the ISP network 432 to wireline media devices 408 or wireless communication devices 416.

Communication system 400 can also provide for all or a portion of the computing devices 430 to function as a media content server (herein referred to as server 430). The server 430 can use computing and communication technology to deliver program content and advertising content including personalized advertisements, which can include among other things, multicasting the program content and unicasting the personalized advertisements. For instance, multicasting and unicasting by server 430 can be similar to the functions described above with reference to FIGS. 2 and 3. The media processors 406 and wireless communication devices 416 can be provisioned with software functions to utilize the services of server 430. For instance, the functions of media processors 406 and wireless communication devices 416 can be similar to the functions of media processor 101 described above with reference to FIG. 1.

Multiple forms of media services can be offered to media devices over landline technologies such as those described above. Additionally, media services can be offered to media devices by way of a wireless access base station 417 operating according to common wireless access protocols such as Global System for Mobile or GSM, Code Division Multiple Access or CDMA, Time Division Multiple Access or TDMA, Universal Mobile Telecommunications or UMTS, World interoperability for Microwave or WiMAX, Software Defined Radio or SDR, Long Term Evolution or LTE, and so on. Other present and next generation wide area wireless access network technologies can be used in one or more embodiments of the subject disclosure.

FIG. 5 depicts an illustrative embodiment of a communication system 500 employing an IP Multimedia Subsystem (IMS) network architecture to facilitate the combined services of circuit-switched and packet-switched systems. Communication system 500 can be overlaid or operably coupled with system 100 of FIG. 1 and communication system 400 as another representative embodiment of communication system 400. In particular, system 500 can perform a method comprising encoding, by a server comprising a processor, media content to generate a plurality of media content files, each having a media content filename and a media content uniform resource locator. The method also comprises receiving a channel request from a client media processor, and generating a playlist for use by the client media processor. The playlist is mapped to the requested channel, and the playlist includes a personalized content filename and a personalized content uniform resource locator for a personalized content file; the personalized content file is not included in the plurality of media content files. The method further comprises receiving a file request from the client media processor in accordance with the playlist, multicasting the plurality of media content files so that the client media processor receives the plurality of media content files, and delivering the personalized content file to the client media processor to enable presentation of personalized content in accordance with the playlist.

Communication system 500 can comprise a Home Subscriber Server (HSS) 540, a tElephone NUmber Mapping (ENUM) server 530, and other network elements of an IMS network 550. The IMS network 550 can establish communications between IMS-compliant communication devices (CDs) 501, 502, Public Switched Telephone Network (PSTN) CDs 503, 505, and combinations thereof by way of a Media Gateway Control Function (MGCF) 520 coupled to a PSTN network 560. The MGCF 520 need not be used when a communication session involves IMS CD to IMS CD communications. A communication session involving at least one PSTN CD may utilize the MGCF 520.

IMS CDs 501, 502 can register with the IMS network 550 by contacting a Proxy Call Session Control Function (P-CSCF) which communicates with an interrogating CSCF (I-CSCF), which in turn, communicates with a Serving CSCF (S-CSCF) to register the CDs with the HSS 540. To initiate a communication session between CDs, an originating IMS CD 501 can submit a Session Initiation Protocol (SIP INVITE) message to an originating P-CSCF 504 which communicates with a corresponding originating S-CSCF 506. The originating S-CSCF 506 can submit the SIP INVITE message to one or more application servers (ASs) 517 that can provide a variety of services to IMS subscribers.

For example, the application servers 517 can be used to perform originating call feature treatment functions on the calling party number received by the originating S-CSCF 506 in the SIP INVITE message. Originating treatment functions can include determining whether the calling party number has international calling services, call ID blocking, calling name blocking, 7-digit dialing, and/or is requesting special telephony features (e.g., *72 forward calls, *73 cancel call forwarding, *67 for caller ID blocking, and so on). Based on initial filter criteria (iFCs) in a subscriber profile associated with a CD, one or more application servers may be invoked to provide various call originating feature services.

Additionally, the originating S-CSCF 506 can submit queries to the ENUM system 530 to translate an E.164 telephone number in the SIP INVITE message to a SIP Uniform Resource Identifier (URI) if the terminating communication device is IMS-compliant. The SIP URI can be used by an Interrogating CSCF (I-CSCF) 507 to submit a query to the HSS 540 to identify a terminating S-CSCF 514 associated with a terminating IMS CD such as reference 502. Once identified, the I-CSCF 507 can submit the SIP INVITE message to the terminating S-CSCF 514. The terminating S-CSCF 514 can then identify a terminating P-CSCF 516 associated with the terminating CD 502. The P-CSCF 516 may then signal the CD 502 to establish Voice over Internet Protocol (VoIP) communication services, thereby enabling the calling and called parties to engage in voice and/or data communications. Based on the iFCs in the subscriber profile, one or more application servers may be invoked to provide various call terminating feature services, such as call forwarding, do not disturb, music tones, simultaneous ringing, sequential ringing, etc.

In some instances the aforementioned communication process is symmetrical. Accordingly, the terms “originating” and “terminating” in FIG. 5 may be interchangeable. It is further noted that communication system 500 can be adapted to support video conferencing. In addition, communication system 500 can be adapted to provide the IMS CDs 501, 502 with the multimedia and Internet services of communication system 400 of FIG. 4.

If the terminating communication device is instead a PSTN CD such as CD 503 or CD 505 (in instances where the cellular phone only supports circuit-switched voice communications), the ENUM system 530 can respond with an unsuccessful address resolution which can cause the originating S-CSCF 506 to forward the call to the MGCF 520 via a Breakout Gateway Control Function (BGCF) 519. The MGCF 520 can then initiate the call to the terminating PSTN CD over the PSTN network 560 to enable the calling and called parties to engage in voice and/or data communications.

It is further appreciated that the CDs of FIG. 5 can operate as wireline or wireless devices. For example, the CDs of FIG. 5 can be communicatively coupled to a cellular base station 521, a femtocell, a WiFi router, a Digital Enhanced Cordless Telecommunications (DECT) base unit, or another suitable wireless access unit to establish communications with the IMS network 550 of FIG. 5. The cellular access base station 521 can operate according to common wireless access protocols such as GSM, CDMA, TDMA, UMTS, WiMax, SDR, LTE, and so on. Other present and next generation wireless network technologies can be used by one or more embodiments of the subject disclosure. Accordingly, multiple wireline and wireless communication technologies can be used by the CDs of FIG. 5.

Cellular phones supporting LTE can support packet-switched voice and packet-switched data communications and thus may operate as IMS-compliant mobile devices. In this embodiment, the cellular base station 521 may communicate directly with the IMS network 550 as shown by the arrow connecting the cellular base station 521 and the P-CSCF 516.

Alternative forms of a CSCF can operate in a device, system, component, or other form of centralized or distributed hardware and/or software. Indeed, a respective CSCF may be embodied as a respective CSCF system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective CSCF. Likewise, other functions, servers and computers described herein, including but not limited to, the HSS, the ENUM server, the BGCF, and the MGCF, can be embodied in a respective system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective function, server, or computer.

The server 430 of FIG. 4 can be operably coupled to communication system 500 for purposes similar to those described above. Server 430 can provide services to the CDs 501, 502, 503 and 505 of FIG. 5, which can be adapted with software to utilize the services of the server 430. Server 430 can be an integral part of the application server(s) 517, which can be adapted to the operations of the IMS network 550.

For illustration purposes only, the terms S-CSCF, P-CSCF, I-CSCF, and so on, can be server devices, but may be referred to in the subject disclosure without the word “server.” It is also understood that any form of a CSCF server can operate in a device, system, component, or other form of centralized or distributed hardware and software. It is further noted that these terms and other terms such as DIAMETER commands are terms can include features, methodologies, and/or fields that may be described in whole or in part by standards bodies such as 3^(rd) Generation Partnership Project (3GPP). It is further noted that some or all embodiments of the subject disclosure may in whole or in part modify, supplement, or otherwise supersede final or proposed standards published and promulgated by 3GPP.

FIG. 6 depicts an illustrative embodiment of a web portal 602 of a communication system 600. Communication system 600 can be overlaid or operably coupled with system 100 of FIG. 1, communication system 400, and/or communication system 500 as another representative embodiment of system 100, communication system 400, and/or communication system 500. The web portal 602 can be used for managing services of system 100 and communication systems 400-500. A web page of the web portal 602 can be accessed by a Uniform Resource Locator (URL) with an Internet browser using an Internet-capable communication device such as those described in FIGS. 4-5. The web portal 602 can be configured, for example, to access a media processor 406 and services managed thereby such as a Digital Video Recorder (DVR), a Video on Demand (VoD) catalog, an Electronic Programming Guide (EPG), or a personal catalog (such as personal videos, pictures, audio recordings, etc.) stored at the media processor 406. The web portal 602 can also be used for provisioning IMS services described earlier, provisioning Internet services, provisioning cellular phone services, and so on.

The web portal 602 can further be utilized to manage and provision software applications to adapt these applications as may be desired by subscribers and/or service providers of system 100 and communication systems 400-500. For instance, users of services provided by server 150 or server 430 can log into their online accounts and provision the server 150 or server 430 with features such as user profiles, provide contact information to the server to enable it to communicate with devices described in FIGS. 1, 4 and 5, and so on. Service providers can log onto an administrator account to provision, monitor and/or maintain system 100 of FIG. 1 or server 430.

FIG. 7 depicts an illustrative embodiment of a communication device 700. Communication device 700 can serve in whole or in part as an illustrative embodiment of the devices depicted in FIG. 1 and FIGS. 4-5, and can be configured to perform portions of method 300 of FIG. 3.

Communication device 700 can comprise a wireline and/or wireless transceiver 702 (herein transceiver 702), a user interface (UI) 704, a power supply 714, a location receiver 716, a motion sensor 718, an orientation sensor 720, and a controller 706 for managing operations thereof The transceiver 702 can support short-range or long-range wireless access technologies such as Bluetooth®, ZigBee®, WiFi, DECT, or cellular communication technologies, just to mention a few (Bluetooth® and ZigBee® are trademarks registered by the Bluetooth® Special Interest Group and the ZigBee® Alliance, respectively). Cellular technologies can include, for example, CDMA-1X, UMTS/HSDPA, GSM/GPRS, TDMA/EDGE, EV/DO, WiMAX, SDR, LTE, as well as other next generation wireless communication technologies as they arise. The transceiver 702 can also be adapted to support circuit-switched wireline access technologies (such as PSTN), packet-switched wireline access technologies (such as TCP/IP, VoIP, etc.), and combinations thereof

The UI 704 can include a depressible or touch-sensitive keypad 708 with a navigation mechanism such as a roller ball, a joystick, a mouse, or a navigation disk for manipulating operations of the communication device 700. The keypad 708 can be an integral part of a housing assembly of the communication device 700 or an independent device operably coupled thereto by a tethered wireline interface (such as a USB cable) or a wireless interface supporting for example Bluetooth®. The keypad 708 can represent a numeric keypad commonly used by phones, and/or a QWERTY keypad with alphanumeric keys. The UI 704 can further include a display 710 such as monochrome or color LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode) or other suitable display technology for conveying images to an end user of the communication device 700. In an embodiment where the display 710 is touch-sensitive, a portion or all of the keypad 708 can be presented by way of the display 710 with navigation features.

The display 710 can use touch screen technology to also serve as a user interface for detecting user input. As a touch screen display, the communication device 700 can be adapted to present a user interface with graphical user interface (GUI) elements that can be selected by a user with a touch of a finger.
